Sustainable development

Nowadays we live better thanks to technology. Technology is used in our lifes in several ways. For instance, communications technology, such as mobile telephones, Internet or computer networks, has made it possible that we are able to communicate with each other easily. Internet lets us get a lot of information without difficulty instead of having to go to libraries for instance. Internet provides us also with an e-mail service that let us send messages all around the world without the postacard's delay.

Computers and Computer's Networks, such as Internet, have improved our lifes

Besides, we have several household appliances at home. Nowadays nobody can imagine our life without a fridge or without a washing machine. The fridge frees us from going shopping everyday and washing machines let us save a lot of time. Of course, transport technology has to be considered as well. Since cars were invented, they have improved a lot, and now they are faster and more secure than before. Thus we can move from one place to another easily. Besides, we can't forget trains and planes, more and more fast and secure. Trains and planes let us travel long distances in a comfortable way.

Therefore, technology has made our life easier and more comfortable. However, there is an important drawback: the power consumption. Cars, computers consume power, which they transform into heat. This heat makes the Earth's temperature increase. This increase of temperature can be a serious threat for the environment. Moreover, energy have to be obtained in such a way that cars, trains and electronic devices can use it. Therefore, nuclear power stations and power stations have had to be built. Nevertheless, nuclear power stations and power stations pollute the environment.

In summary, we can state that technology has made our lives easier. Nonetheless technology has an important drawback: the environment's pollution. Therefore, so as to preserve our planet, mankind has to find a balance between comfort and environment's preservation. A more responsible consume of energy and the development of renewable energies, specially nuclear fusion, could help us to get this balance.
